Connect internal and external structures to functions.
Bring the unit skills together
Use these 4 new cases to check your reasoning. Choices are temporary and are not saved to an account, sent to staff or recorded as school grades. Download your current review choices before leaving or reloading.

Use the skills in a new task
Draw or write four parts for “Organism Systems and Sensing”—one pretend example from each lesson. In each part, show what happened, give your answer, and say which clue helped you. If the question gives numbers, show your working too. Finish with one thing the practice case does not tell us. You may say your answers aloud.
Work on paper or in your own document. Explain the choices you made.
- Choose one pretend example from each of the four lessons.
- Name what each example shows.
- If the example gives numbers, show your calculation and unit. Otherwise, say which clue explains your answer.
- Say that the case details are supplied for practice; they are not your own real-life observations.
- Say one thing the example does not tell us, or one change that could give a different answer.
Compare with a model response
Panel 1: Which scientific label fits the specifically described step or feature? Supplied case: Water uptake from soil. Result: root. Reasoning: The answer is root. In the notes, it means “absorbs water and dissolved minerals.” Parts work together in a plant system. Roots absorb water, stems transport, leaves capture light and many flowers participate in reproduction. A part’s function is more useful than its appearance alone. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 2: Which scientific label fits the specifically described step or feature? Supplied case: Food nutrients enter the body. Result: digestive. Reasoning: The answer is digestive. In the notes, it means “breaks food down and absorbs nutrients.” Body systems interact; each listed function is simplified. This is general anatomy education, not diagnosis. Oxygen and nutrients must reach cells and wastes must be managed. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 3: Which scientific label fits the specifically described step or feature? Supplied case: A light changes in brightness. Result: stimulus. Reasoning: The answer is stimulus. In the notes, it means “change that can be detected.” Sensory receptors detect stimuli, and signals can lead to responses. A model includes stimulus, detection, processing and response. Memory can also affect a response; the model is not a complete brain description. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 4: Which scientific label fits the specifically described step or feature? Supplied case: A hard outer shell. Result: structure. Reasoning: The answer is structure. In the notes, it means “the physical part.” A claim should name the part and explain its function. A label alone is not an explanation. Supplied descriptions distinguish direct observations from inferred functions and missing evidence. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified.
A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
